The solar corona can cause unstable phases for sources too close to the Sun. SCHED provides warnings at individual scans for distances less than 10 degrees. The distance from the Sun to each source in this schedule is: Source Sun distance (deg) J2237+4216 49.0 GJ873 48.7 J0110+5404 45.9 GJ53B 46.7 J0124+5618 48.1 J0237+2848 27.9 3C454.3 36.0 J2255+4202 46.1 Barry Clark estimates from predictions by Ketan Desai of IPM scattering sizes that the Sun will cause amplitude reductions on the longest VLBA baselines at a solar distance of 60deg F^(-0.6) where F is in GHz.
